Thanks, James, for the equation.

So, for a 1/8 scale King Tiger that weighs 140,000 lbs the equation would be:

140,000/8 = 17,500/8 = 2,187.5/8 = 273.44 lbs

Thus, my 1/8 KT should weigh roughly 273 lbs!

That sounds about right.

Mine weighs around 70 lbs with the two 12v batteries. Except for a few parts like the drive sprocket, idler wheels, and the aluminum track, it's made of composite materials that are strong but weigh much less than steel. This was done on purpose -- the lighter the tank, the more reliable the drive and transmission, and a smaller power plant is required.

Some manufacturers like Armortek of Great Britain make theirs in almost all metal. The result is a heavier tank and more in weight scale. (I believe their 1/6 Tiger I weighs around 165 lbs. -- the scale weight is around 230 lbs, I believe.)

So, even if you would manufacture the scale tank in all-metal, you would be hard pressed to achieve a true scale weight.

Lots to think about and thanks again for the equation.

Cheers...
